Abstract
Little is known about the cuticle of grass leaves and its formation during epidermal cell development. Based on our own observations, we propose that (i) the cuticle attains most of its final physical properties in the 10-24 h between full expansion of an epidermal cell and its emergence into dry air, and that (ii) cuticle formation is regulated by differences in tissue concentration of CO2 between emerged (low), emerging (intermediate) and expanding (high) portion of the blade. Tissue CO2-concentration will be manipulated and cuticle permeance to water and lipid/wax composition will be analysed. Gene probes and cuticular wax mutants of barley and maize will be used to relate changes in cuticle properties to changes in gene expression.
